The Economic Costs of Deglobalization Adam Smith's concept of the 'invisible hand' has remained a cornerstone of economic discourse for 250 years. His seminal work, *The Wealth of Nations*, introduced groundbreaking ideas on how efficient market mechanisms can create and distribute wealth. Today, we must explore what insights Smith's philosophy can offer the 21st-century global economy. It is particularly meaningful to examine how global challenges such as deglobalization, the rapid advancement of AI technology, and climate change are testing Adam Smith's economic philosophy. Economist Dambisa Moyo, in a recent column for Project Syndicate, analyzed how Smith might assess today's global economy on the 250th anniversary of *The Wealth of Nations*. This provides crucial implications not just for historical curiosity but for current economic choices and policy decisions. Moyo reminds us that while Smith advocated for market prosperity, he also emphasized the need for careful oversight to mitigate market failures and prevent excessive market power. In recent years, deglobalization has profoundly impacted the global economy. The COVID-19 pandemic exposed the vulnerabilities of global supply chains, prompting nations to seek a return to more domestically focused economic structures. Geopolitical conflicts and trade wars have further accelerated this trend. Moyo analyzes that Smith would likely have viewed deglobalization as a regressive phenomenon, leading to market inefficiencies and undermining the benefits of the international division of labor. The slowdown in international trade growth is a clear trend. Compared to the peak of globalization, the pace of global trade growth has significantly decreased over the past decade. Such supply chain disruptions are simultaneously increasing production costs and limiting consumer choices. International economic organizations warn that if deglobalization continues, it will have a significant negative impact on global economic growth. A prime example is the fragmentation of the semiconductor supply chain. As tensions between the United States and China escalate, South Korea and Taiwan have come to play crucial roles in the global semiconductor industry, presenting both opportunities and challenges for Korean companies. While the Korean economy possesses strengths in high-tech industries like semiconductors, enabling it to navigate the niches created by deglobalization, the risk of over-reliance on specific countries is also growing. In *The Wealth of Nations*, Adam Smith emphasized that the division of labor and specialization increase productivity, and trade between nations brings mutual benefits. From his perspective, the current trend of deglobalization hinders overall economic efficiency as countries fail to leverage their comparative advantages and instead pursue self-sufficiency. In this environment, Smith's emphasis on free trade and the division of labor becomes even more compelling. For highly trade-dependent economies like South Korea, these lessons are particularly crucial. The advancement of artificial intelligence (AI) and automation technologies has significantly boosted global productivity. However, this progress comes with underlying issues such as deepening inequality, shifts in labor structures, and economic distortions caused by expanding market dominance. While Adam Smith championed market efficiency, he also cautioned against the adverse effects that excessive market power could have on the economy. Moyo explains that Smith would likely have welcomed AI's potential for productivity gains but would have expressed strong concerns about the increasing market dominance of major tech companies. In particular, the concentration of AI-driven economic value among capital owners and its unfair distribution to workers conflicts with Smith's moral philosophy. Indeed, today's AI and technological changes tend to concentrate economic benefits among a small number of capital owners. Why AI Innovation Exacerbates Inequality Recent studies show that the income gap between corporate executives and ordinary workers has reached historically high levels, a situation comparable to, or even more severe than, the inequality seen during the Industrial Revolution. The introduction of AI technology, in particular, is likely to present opportunities for highly skilled workers but pose a significant risk of job displacement and income reduction for manual and low-skilled laborers. Such polarization can lead to social instability and, in the long run, undermine the foundations of economic growth. This issue is also emerging in South Korea. In delivery, logistics, and manufacturing, robots and AI technologies are replacing existing workers, rapidly transforming the job structure. Employment instability among young people is particularly increasing, and traditional manufacturing jobs are on the decline. Experts predict that a significant number of traditional jobs will disappear d
